Question

3.
Calculate the number of electrons constituting one coulomb of charge.
​

Answer 1

Answer:

6.25 x 10^18 electrons

Explanation:

Relation between number of electrons and charge is

q = n e

q = charge , n = number of electrons  and  e = 1.6 x 10^(-19)C = charge of electron

So, applying the relation

q = 1 C , e = 1.6 x 10^(-19)C , n = ?

q = n e

1 = n x 1.6 x 10^(-19)

=> n = 1 / (1.6 x 10^(-19))

n = (1 x 10^19) / 1.6

n = 0.625 x 10^19

  = 6.25 x 10^18 electrons

Hope it is useful...

Answer 2

Answer:

one electron possesses a charge of 1.6 *10-19C , that is 1.6*10-19Cof charge is contained in 1 electron. therefore .6*1018 electrons constitute one coulomb of charge.
